Figure 4.

(A) Amino acid sequence alignment of HpTBP with those of TBPs from other sea urchin species (Sp, S.purputatus; Lv, L.variegatus) and yeast (Sc, S.cerevisiae). An asterisk denotes the boundary between the N-terminal non-conserved region and the C-terminal highly conserved region. Dashes indicate gaps introduced to maintain optimal alignment. Shading indicates identical residues. (B) Schematic representation of the comparison of the four TBPs. The C-terminal highly conserved regions are shaded. The percentage of identical residues when compared with HpTBP are calculated individually for the N- and C-terminal regions and are shown in each rectangle.
